Formally Modeling the Terrapin Attack on SSH

The Terrapin attack against SSH channel integrity USENIX Security 2024 used a novel attack vector: attacks on the channel state. Surprisingly, not all AEAD modes of SSH were equally affected by this attack, and it remained an open question if "unaffected" meant "secure". Existing formal models fo...

MGASA-2026-0179 Updated golang-x-crypto & golang-x-sys-devel packages fix security vulnerability

fixes a protocol weakness in the golang.org/x/crypto/ssh package that allowed a MITM attacker to compromise the integrity of the secure channel before it was established, allowing them to prevent transmission of a number of messages immediately after the secure channel was established without...

MGASA-2026-0066 Updated trilead-ssh2 packages fix security vulnerabilities

TencentOS Server 3: libssh (TSSA-2024:0056)

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2024:0056 advisory. Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:...

ssh: Prefix truncation attack on Binary Packet Protocol (BPP)

A flaw was found in the SSH channel integrity. By manipulating sequence numbers during the handshake, an attacker can remove the initial messages on the secure channel without causing a MAC failure. For example, an attacker could disable the ping extension and thus disable the new countermeasure ...
